This wiring harness assembly routes power and signals between the washer's main control and key components so the machine operates correctly. It replaces a damaged or burnt harness to restore reliable electrical connections. What it does:

• Provides the factory electrical connections between the main control board and components like the motor, lid switch, and valves
• Restores intermittent or failed circuits caused by frayed wires, broken connectors, or heat damage
• Helps resolve symptoms such as washer not starting, unresponsive control functions, or intermittent operation tied to wiring faults
• Matches OEM connector types and routing for a direct replacement

• Disconnect power at the breaker before starting any repair to avoid shock or damage
• Compare the replacement harness to the original for connector types and lengths before installation
• Route and secure the harness following factory clips and channels to prevent chafing or pinching
